Jason Liam Cooper

He had bullied, stalked and harassed the 33-year-old care worker for months before the fateful night in August 2017 when she left the Golden Lion pub in Denbigh with her friend David Roberts for the last time.

Cooper sprinted up Denbigh High Street and stabbed her twice from behind and once in the chest. David Roberts tried to defend her but was also stabbed by Cooper.

He pleaded at Mold Crown Court that he had abnormal mental functioning due to alcohol addiction. He arrogantly sat shaking his head as the overwhelming evidence of his guilt was laid out in front of the jury.

The couple, who were separated, had enjoyed a day out at Chester Races together just two days before Mrs Jordan was murdered.

During the trip, they encountered a man who Jordan believed his wife was having an affair with. Police found no evidence to substantiate this belief but, at Caernarfon Crown Court, Judge Rhys Rowlands said he was satisfied this acted as a trigger to the killing.

Gordon Cole QC, defending, said: "He has instructed me to say, in public, how sorry and remorseful he is. And to this day he has no idea how the events unfolded and culminated last July. He is massively mindful of what he has done to his children."

Elizabeth ‘Betty’ Jordan

He was found dead in custody at HMP Altcourse on July 6. An independent investigation was opened immediately by the Prisons and Probation Ombudsman, but has yet to report.

Within a matter of weeks of the infant's death, as she received treatment at psychiatric units, she began to give the first clues that all was not as it seemed.

Turtle, 22 and from Shotton, made various disclosures as to what she had done, saying she had killed her son, that she was a murderer, and that she’d been hearing voices at the time telling her she needed help.

A review was also announced into the role that various agencies played in Turtle's life prior to the killing.

The baby’s grandmother Kathleen Hughes said in a victim impact statement read to the court by prosecuting barrister David Elias QC that she regarded Turtle as "pure evil".

She added: "As a family we are all still suffering every day and we all feel in our own different way despair at what has happened.

"We will continue to support each other in every possible way that we can. James will always be our little angel."

Lesley Baines and David John Woods

Baines and Woods were sentenced to a total of 53 years at Mold Crown Court in May this year for the murder of Matthew Cassidy, 19, in a turf war over drugs 12 months earlier.

Baines, 48 at the time of his sentencing and from Connah's Quay, was given a minimum term of 27 years in jail. Woods, who was 20 and from Douglas Place, Liverpool, was handed a minimum 26-year term.

The pair had gone to flats in Connah's Quay with "significant pre-meditation – it was not a spontaneous outburst of violence", said trial Judge Clive Lewis.

Redvers James Bickley

In September 2017, the KFC worker snapped and brutally stabbed Tyler, 25, to death with a kitchen knife, repeatedly going back to attack her.

Her sisters Shannen and Cody and their father Paul fought bravely to save both Tyler and themselves as crazed Bickley grunted "Red's revenge, Red's return" in a low, menacing voice - as described by witnesses in Llys Aderyn Du in Rhyl, where he and Tyler lived.

His attack started after the women, who had been having a "girl's night in" together before Bickley entered the house, returned from a drive out they embarked on because of the atmosphere he had created.
